Phase - Locked Loops Demystified
Over the past decade, Phase-Locked Loops (PLLs) have become an integral part of the modern ASIC design. PLLs provide the clocks that sequence the operation of the various blocks on an ASIC chip as well as synthesize their communications. There are various types of PLLs targeting specific applications. Clock generator PLLs are capable of large frequency multiplication. They are primarily used to...
متن کاملA Verilog Implementation of Low Power Interference Reduction Technique
In this paper, as the operating frequency of electronic systems increases, the electromagnetic interference (EMI) effect becomes a serious problem especially in consumer electronics, microprocessor based systems, and data transmission circuits. The Many approaches have been proposed to reduce EMI, such as shielding box, skewrate control, and spread spectrum clock generator (SSCG). However, the ...
